Project Management is a vast discipline, which over the years has come to embrace contents from various fields that have also proved relevant for the good management of projects. The book identifies the factors that are decisive in this direction, underlining the importance of integrating the methodological and organizational aspects of Project Management. Knowing how to manage projects provides companies with an important competitive advantage, since the contraction of product life cycles reduces the time to return on investment and this means less tolerance for errors. From the main characteristics of the projects to the identification of the fundamental factors for their success, from the concept of life cycle to the behaviors that accompany each phase, from the management of the stakeholders to that of the physical and economic resources, the book illustrates every aspect through numerous examples and references to concrete cases. The book presents a new and in-depth chapter on the Agile approach, with a description of its birth, its various applications and some key operational practices. A focus on the management of multi-project environments and a checklist for the evaluation of the robustness of a project in each phase of its life, close the discussion.
